Problems solved by technology

Most of the energy is transferred from the head to the golf ball, however, some energy is lost as a result of the collision.
However, this leads to greater deformations in the golf ball, and thus increases in the energy transfer problem.
Although the prior art has disclosed many variations of multiple material club heads, the prior art has failed to provide a multiple material club head with a high coefficient of restitution, greater forgiveness for the typical golfer and / or optimized mass properties.

Embodiment Construction

[0074]As shown in FIG. 1, a golf club is generally designated 40. The golf club 40 has a golf club head 42. Engaging the club head 42 is a shaft 48 that has a grip 50, not shown, at a butt end 52 and is inserted into a hosel 54 at a tip end 56.

[0075]As shown in FIGS. 1A–8, the club head 42 is generally composed of a face component 60 and an aft-body 61. The aft-body is preferably composed of an upper section 200 and a lower section 202, which are joined together to form the aft-body 61. The aft-body 61 preferably has a crown portion 62 and a sole portion 64. The golf club head 42 is preferably has a heel end 66 nearest the shaft 48, a toe end 68 opposite the heel end 66, and a rear end 70 opposite the face component 60.

[0076]The face component 60 is generally composed of a single piece of metal, and is preferably composed of a forged metal material. More preferably, the forged metal material is a forged titanium material. Such titanium materials include pure titanium and titanium al...

Abstract

A golf club (40) having a club head (42) with a face component (60) and an aft-body (61) is disclosed herein. The face component (60) has a striking plate portion (72) and a return portion (74). The aft-body (61) is composed of a crown portion (62), a sole portion (64) and optionally a ribbon section (90). The face component (60) is composed of a metal material, and the aft-body (61) is composed of a metal material selected from the group consisting of magnesium alloys, aluminum alloys, magnesium and aluminum. The striking plate portion (72) preferably has an aspect ratio less than 1.7. The striking plate portion (72) preferably has concentric regions of thickness with the thickness portion in the center (102). The club head (42) has a volume in the range of 290 cubic centimeters to 600 cubic centimeters, a weight in the range of 165 grams to 300 grams, and a striking plate portion (72) surface area in the range of 4.00 square inches to 7.50 square inches.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]Not ApplicableFEDERAL RESEARCH STATEMENT[0002]Not ApplicableBACKGROUND OF INVENTION[0003]1. Field of the Invention[0004]The present invention relates to a golf club head with a face component composed of a metal material, and an aft-body composed of a light-weight material. More specifically, the present invention relates to a golf club head with a face component composed of a metal material for a more efficient transfer of energy to a golf ball at impact, and a low density metallic aft-body to control the mass distribution.[0005]2. Description of the Related Art[0006]When a golf club head strikes a golf ball, large impacts are produced that load the club head face and the golf ball. Most of the energy is transferred from the head to the golf ball, however, some energy is lost as a result of the collision. The golf ball is typically composed of polymer cover materials (such as ionomers) surrounding a rubber-like core. These softer polymer...
